Compute each part of given problem:
Problem: A uniform electric field with a magnitude of 6100N/C points in the positive x direction.
Part I: Find the change in electric potential energy when a +19.0-µC charge is moved 6.50cm in the positive x direction.
Part II: Find the change in electric potential energy when a +19.0-µC charge is moved 6.50cm in the negative x direction.
Part III: Find the change in electric potential energy when a +19.0-µC charge is moved 6.50cm in the positive y direction.
I just want the right solution; express your answer using one significant figure. Thanks.
